The Phantasy Hack
WHAT IS THIS?
The Phantasy Hack is a tabletop roleplaying game designed to evoke the mood and tone of a certain series of JRPG videogame titles.
THE CORE MECHANISM
Whenever characters attempt something where the outcome is uncertain (e.g.¸ shooting a biomonster¸ dodging a biomonster¸ &c.)¸ their player rolls d20 and succeeds if the score on the dice is equal to or lesser than the attribute being tested.
Biomonsters don't make tests: instead a character must defend against them. Biomonsters only roll for initiative and damage.
